How to make an object emit light streaks
This can be done through compositing 
you can do this in blender itself by adding glare node and switching to streaks and some few tweaks 
another way is switching to any compositing software like after effects and add lens flare manually like in after effects optical flares is the perfect option.
Earlier there was a Add-on in Blender itself that was giving a facility to provide you a lens flare but after releasing 2.8 version of blender this add-on lost somewhere 
I mean developers did not updated that add-on to 2.8
